Answer:

C. (a)-(iii) ,(b) -(i) , (c)- (iv), (d) - (ii)

• Etaerio of achenes: An etaerio is a cluster of simple fruits developing from a single flower with multiple separate carpels. In Lotus, each carpel develops into a single-seeded, indehiscent fruit called an achene, which is embedded in the fleshy receptacle.

• Etaerio of berries: In Annona (custard apple), the flower has many separate carpels, and each carpel develops into a berry-like fruitlet. These fruitlets fuse together to form a composite or multiple fruit.

• Etaerio of drupes: Rubus (raspberry, blackberry) has a flower with multiple carpels. Each carpel develops into a small drupe (a drupelet). The cluster of these small drupes forms a composite fruit.

• Etaerio of follicles: In Calotropis (milkweed), the flower has two separate carpels. After fertilization, each carpel develops into a follicle, which is a dehiscent fruit that splits open along one seam to release seeds.
